If POSIX can be loaded, then _exit is used on exec failure.
exec @cmd or do {
carp "$Me: exec of @cmd failed";
eval { require POSIX; POSIX::_exit(255); };
exit 255;
};
Using _exit should avoid the problem because _exit doesn't allow destructors to be run.
>perl -MPOSIX -le"DESTROY{print q{foo}}$o=bless{};$ARGV[0]?_exit 1:exi
+t 1" 1
>perl -MPOSIX -le"DESTROY{print q{foo}}$o=bless{};$ARGV[0]?_exit 1:exi
+t 1" 0
foo
Could there be a problem loading POSIX?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
